I believe the validator used to flag using the REV attribute on A and LINK elements as obsolete, but no longer does this. The REV attribute is still marked as non-conforming in the HTML5  CR and nightly specs. The language looks the same in all the versions:

"11.2 Non-conforming features"
"The following attributes are obsolete (though the elements are still part of the language), and must not be used by authors:
"rev on a elements"
"rev on link elements"

http://www.w3.org/html/wg/drafts/html/CR/obsolete.html#non-conforming-features
http://www.w3.org/TR/2014/CR-html5-20140204/obsolete.html#non-conforming-features
http://www.w3.org/html/wg/drafts/html/master/obsolete.html#non-conforming-features

Looking into this a bit deeper, I think there might be a mismatch between the HTML5 CR and the RFDa recommendation (which says "RDFa supports the use of @rel and @rev on any element.")
http://www.w3.org/TR/2013/REC-rdfa-core-20130822/#examples
http://www.w3.org/TR/2013/REC-rdfa-core-20130822/#A-rev

There are also 4 tests in the conformance checker test suite that use the REV attribute, with the naming indicating validators should not flag a conformance error:
html-rdfa/0006-isvalid.html
html-rdfa/0007-isvalid.html
html-rdfa/0009-isvalid.html
html-rdfa/0010-isvalid.html

So, what's the correct behaviour - is this conforming or non-conforming?

Best Regards
